ABSTRACT
AIM: Very few oral leiomyomas have been reported in the literature, especially in children. The aim of this article was to present a very rare new case of leiomyoma in the chin, in a seven-year-old black male, and to explain its clinical and histological features. CASE REPORT: A seven-year-old black male patient presented with a swelling mass of diameter 2.5 x 3.0 cm in the lower anterior area of the chin. The tumor was firm, painless, non-fixed and well-defined, with normal mucosa overlying it. Fine-needle aspiration prior to surgery was negative. The surgical access was intraoral and the mass was located under the skin and below the periosteal bone, within the musculature. The histological and immunohistochemical studies diagnosed an oral leiomyoma. The clinical appearance of leiomyomas is very difficult to differentiate from other mesenchymal tumors. Histological and immunohistochemical studies were crucial for achieving a definitive diagnosis. Eighteen months after the excision of the lesion, no signs of recurrence were observed. The successful treatment had several objectives, including removing the lesion with success and providing the patient with an aesthetic appearance.
